Standards & References

  • ASTM D3350 Standard Specification for Polyethylene Plastics Pipe and Fittings Materials
  • ASTM D3485 Standard Specification for Coilable High Density Polyethylene (HDPE) Cable in Conduit (CIC)
  • ASTM F2160 Standard Specification for Solid Wall High Density Polyethylene (HDPE) Conduit Based on Controlled Outside Diameter (OD)
  • UL 1990 Standard for Nonmetallic Underground Conduit with Conductors
  • NEMA TC-7 Smooth-Wall Coilable Electrical Polyethylene Conduit

Construction

  • Manufactured by continuously extruding HDPE loosely around the cable assembly with no adhesion between the conduit and the cable, thus leaving the cables free in the conduit
  • Schedule 40
  • All cables are installed as single conductors or paralleled in HDPE conduit
  • Lubrication is applied to the cable, allowing for cables to be pulled out and replaced if necessary
